and the cylindrical ortion of the shaft. A lever 16 is provide with a central opening corresponding in cross section to the square portion of the shaft and fitting thereover, the lever being supported by the shoulders and secured in place by a nut 18. The ends of the levers 16 are received between spaced lugs 19 of integrally threaded socketslt) and Z1, and bolts 22 traverse the lugs and the ends of the lever. Rods 23, 211, are threaded into the sockets 20, 21, and the opposite ends of the rods are threaded into sockets 25, .26, each of said sockets being rovided with curved parallel arms 27,28, w ich are pivotally connected to the opposite faces of the disks 29, 30, journaled on a shaft 31 journa-led in bearings 32, secured to the side membersof the casing.

Itwill be evident from the description, that when one of the disks 29, for instance, is rotated in one direction, the lever 16 will be operated to oscillate the shaft 10, whereby to move the switch point in one direction, and

that the operation of the lever through the rod 24 will oscillate the other disk in the opposite direction.

The lever 16 has connected with the center thereof a crank arm 34, which is received be tween lugs on one of the members 36 of a telescoping shaft, the other member 36 being provided with lugs 37, which receive be'- tween them the end of a bracket 38, and bolts 39 connect the lugs 37 and the bracket 38 and also the lugs 35 and the crank arm 34. A spring 40 encircles the telescoping shaft, and each member of the said shaft 18 provided with an annular shoulder 41, adjacent to the lugs against which the endsof the spri bear.

A mechanism is provided for osc' lating eachof the disks, the said mechanism comprising a swinging lever 43, 44, for each disk, the said levers being pivoted at to a rod 46 arranged transversely of the casing, and supported by a plurality of bearings 47, connected with a c1 oss bar 48 arrangedbetween the side members. The end of the swinging lever 43 adjacent to the shaft, is forked as at 49, for receiving the edge of the disk therebetween, and the lower faces of each of the arms of the fork is notched as at 50, for engaging segmental plates 51, secured uponeach face of the disk. The upper face of each of the swinging levers is provided with a cam-shaped surface 52, projecting1 upward casing,

and is adapted to be engaged b mechanism in, the ear to be presentl cseri ed,whereby to swing the owing-in ever downward and oscillate the disk on t e shaft. I Adjacent to the shaft upon which are jonrmilmi the disks, is a crossbar 54, provided with a plurality of vertical openings i throiigh, and slidable in the openings are rods 56, having their upper ends header an at 57, and a spring 58 is arranged between the head of each rod and the cross bar. The head 57 of the rod 56 is immediately beneath the swinging lever 43, in position for engagent by the lever when it is depressed by the operating iiirchanisin, so that the swinging downward of the lever will compress the a wing, am shaped s'urfnee is released the spring vote the swinging lever.

lf deeiri-d, the rod 56 may be provided with a yoke 59, within which the swinging lever is the arms of the yoke being pivoted l'fltfllvtl l, I to the sides ol the lever. The swinging layer may also have an extended end opposite the rod from the disks, and the said extended end may be provided with an opening 60, through which passes a rod 61 pivoted to a bracket 62 on the upper face of the casing, and provided with a not (315 below the extended end of the lover, a spring 64 being arranged between the extended end and the bracket.

1,, Fi 7, l have shown a modified form of swinging lever, comprising a ortion 65 pivoted by one end to the rod before described, and having on its lower face at its opposite end a slideway 66, in which 18 mounted the other portion 67, the said portion being provided with the fork 49 before described. The portion 67 is provided with it hi 08, through which slides a rod 69, having one of its ends connected with the hearing 71 of the swingin r lever, and a 5 ring 72 ed between t e luig 68 and t e bearis inning i 7], The se niental p tes 51 may also be dispensed wit 1, and replaced-by a pm 173 traversing the disk and projecting upon eac 1 face thereof.

The mechanism ust described 18 ada ted for operating a switch point upon one si e of but for operating the switch point opposite side of the track, which 18 generally placed at some littlc listanee from the other Hwiteii point, additional mechanism is provided. A shaft 10", similar in al r npecta to the shaft 10 before described, is jouroilcd in a cross bar 12 arranged between the aide members of the casing, and is connected up to the switch point 7" by a similar mechanism, comprising the link 8 and the crank 9". A similar lever 16 is connected with the upper end of the shaft in precisely the same manner as the lever 16 before derihed, and threaded sockets 20, 31 are connected to the opposite ends of the lever. ltoda 74, 75 are threaded into the sockets 21,

1 when the pressure on the camwill ele- 21*, by one end 'ancT the other ends are threaded into soc 'ets 7o, 77, the said sockets each being provided with a lug 78 received between cars 79, on the ends of rods 80, 81,

slidable through bearings 82, S3 in the cross the disks 29, 30. The upper end of the shaft 10 is provided with a crank arm 34', to which is connected one of the members 36 of a telescoping shaft, similar in all re- 5 acts to the mechanism before described in connection with the other shaft 10. The object of the telescoping shaft with the pring between the members thereof, is to tirow the shafts 10, 10, past the center and to properly retain the switch point in whichr position it is moved.

In Figs. 2, 12 and 13, I show the mechanism connected with the car for operating the swinging levers, the said mechanism comprising a plate 88 secured to the bottom of the platform, having integral therewith four depending brackets 89. Rods 90 extend downward from each end of the platc'88, and secured to the lower ends of the rods is a cross bar 9}, provided with four spaced square op enin s 92 thcrethrough, each 0 said openings eing adapted to receive the s uare portion 93 of a vertically slidable shaft 94, the lower end of the shaft being rovidcd with cars 95 in which is journaled a roller 96. Each of the four shafts 94, is similar in construction and only one will be described. Brackets 97 are secured to the front of the cross bar at spaced intervals, and the upper free edge of each bracket is provided with a plurality of spaced t h 9g and within each notch is ivota ly mounted no, nd of a segmental ever 99, the said levers being arranged in pairs, and ea h.

pair having; their free ends connected together. T ie shaft 94, has-its upper end reduced and made cylindrical, and this ('vlindrical portion is received between a pair of arms segmental shoulders being formed on the shaft between the square )ortion and the cylindrical portion, upon w iieh the lower dges of the arms bear. A collar 1th) is arranged on the shaft above the arms, and the u per end of the shaft is headed as at 101, a a )ring 1023 being arranged between the head of the shaft and the bracket 89 before menti d, the lower end of the bracket being rovided with an opening for receiving the cylindrical portion of the shaft. The connccted ends of each pair of segmental levers w my.

plate 112 slidable transversely of the plate is provided with spaced ears 103, and 1 between the ears is pivoted the lower end of a verticall, liding bar 104, movable through an opening 105 in the plate 88 before mentioned. and provided on its upper end with a treadle 106, by means of which-aniotorman may operate the shaft with his foot. One of the edges of the bar 10- is provic'ed with a plurality of notches 107. adaptedto engage beneath a catch 88", for retaining the shaft in its lowered position. Plates 108 are arranged upon the upper surfaceof the platform. the said plates being provided with openings as shown corresponding to the openings in the lower plate. It will be understood from the description, that when the motor-man desires to throw the switch. he wilLdepress the shaft 94 corresponding to the swinging lever. which he wishes to operate, and as the car passes over the said lever it will be depressed, whereby to oscillate the corresponding disk to swing the vertical shaft and throw the switch point.

in Figs. 16 and 17 is shown the preferred manner of connecting the switch point with the crank arms. A. plate 109 is arranged beneath the switch point. and the said point is l provided with integral ins Ht), 111. one of said pins being receive in an opening in the plate 109, and the other in an opening in a 109. the said plate being cut away to receive the plate 112, and bein; provided with bearings 113 at each end of the cut away portion for retainin the aid plate in lace. The link 8, before described. is pivota it connected with the end of the plate-112.

Plates 114 are arranged l -etween the side members-of the casing and the rails. to int-lose the space tlu-rebetwcen, and additional plates 115 are connected with the ends of thecasing; the upper surface of the said plates being flush with the upper surface of the casing. and extending in eachfllilection therefrom, whereby to afford a ridinp surface for the rollers in the lower ends of the shafts 94. lineof the doors 2, '3. is provided 'with a piarality of locks 116. pach of said locks compri ing n disk pivoted by its center between the door and a bracket HT on the lower face thereof, a portion f the di k being cut away as at UN. to permit tl' dish to pas the door when the cut awa portion is in the proper position. The upp r.cnd of the pivot upon which the di k turns is squared as at Ht. for rct'ciYiug it her. and the squared portion may. have an opening therelhrough toperinit the insertion of an instrument, whereby t iifi the door. The door covering the i swin ing li'HIfl as before stated. i provided with slots through which lie cam-shaped portion f the lt=\4'l' pass, and between (:H'll of the slots is a ridge 121. of approxiniatef the height of the run-shaped portion of He lever to protect the, levers from vehicle wheels crossing the track, and to prevent depression of the swinging levers by such ve- 'cle wheels.

In F i 15, is shown a modification espe cially a apted for underground trolley roads. In the modification, the casing is divided into two portions, one upon each side of the slot, and a single operating shaft 13 contained in each casing. Otherwise the constructaon is precisely the same as in the form first described. and operates in the same manner.
